PC reboots randomly

I guess it has to be option 1. Would that also cause problems with FireFox? I'm sure the problems began only after the RAM upgrade.

Could you elaborate on 1 please. Perhaps with a little info on what could have gone wrong and what I can do to fix it...

A stick of RAM contains several small chips.If one of those small chips is faulty it can cause errors.

If you are using more than one stick try each one separately. By the process of elimination you will be able to tell if you have a faulty stick.

A temporary thing to do is turn off "automatically restart" by accomplishing a right click on My Computer, select Properties, then the Advanced tab. Find Startup and Recovery then click the Settings button and finally remove the check mark on automatically restart.

This won't prevent the computer from freezing but it might give you the opportunity to download and run memtest86. If it is memory, it should show up during that test. If you have multiple memory sticks, you can try one stick at a time to eliminate a bad stick.

I would also consider that the CPU could be overheating. Dust in heatsink veins can create a heating problem.
